Abstract
The axial-flow turbine has a monobloc drum with one or more blade rings protruding from it, each blade having a foot fitting in thedrum. The blades are inserted through openings in the drum in the inwards direction until their feet come up against shoulders in the openings. A support locks the blades of each ring in position and is movable in the peripheral direction, consisting of an annular component of elastic material (14), with a gap in it wider in the peripheral direction than a blade. A closing piece (16) fits in the gap seals it, being removable so a as to allow fitting or removal of a blade through it.
